Stop: C0000135{unable to locate component}

i got this error message: in my toshiba satellite 2450
stop: coooo135{unable to locate component}
this location has failed to start because baseserv was not found. re-installing the application may fix this problem.......

another problem is i dont have the recovery disk and other utility disk that came up with the product...

i have an xp pro installer that is bootable.. but my laptop seems to bypass the cd rom.
it goes directly to the page where in i am ask if loading to safe mode, last known good config, etc... then what ever i choose, im directed to the windows xp loading page then automatically shuts down and on again... on nd off nd on nd off..... with the same process...

i even dis-assembled my 2450 laptop and reseat all sockets, cards, lcd "everything".....

i already changed the boot sequence... cd, fdd,lan, hdd......

dont have floppy drive..

which is defective??? my cd rom? hdd?

what im trying to do is to reinstall os using xp pro...

ope someone can help me....
